摘要
虚拟现实地理信息系统 (VR -GIS)使得地理信息系统 (GIS)的应用和发展方向发生了巨大的变化。结合平时的研究工作 ,在大量参阅文献资料的基础上 ,本文通过对GIS和VR-GIS技术的发展及特点进行分析 ,从海量数据处理技术、虚拟景观的重建和漫游技术、计算机支持的协同工作技术等方面研究了VR -GIS技术的几个热点领域的现状和发展。
Virtual Reality Geographic Information System (VR-GIS)is arousing the tremendous changes of the application and development of Geographic Information System (GIS).Combined with the author's peacetime research,on the basis of lots of literature and data,the development and the characteristic of GIS and VR-GIS technology are analyzed in this paper. From the point of view of Gigabytes data processing technology,virtual landscape reconstruction and cruise, the computer supported cooperative work,etc.,this paper discussed the status quo and development of some hotspot on VR-GIS technology.
